Newest Photoshop CC version is eating gigs of HD space

Latest version of Photoshop CC is eating hard drive space like crazy. Each file I open (between 20-30MB) decreases HD space by 2 gigs. I run out of HD space pretty quickly. Quitting Photoshop gives me all the HD space back.

I’m not sure if it’s an overzealous scratch disk or what. Even if it is, opening a 22MB file shouldn’t take up 2GB on a scratch.

I appreciate the comment. I’ve never had it take up nearly 4GB for every file opened. Currently I’ve got 6 files open and I’ve watched the available HD space go from 35GB to just over 300MB. Now the OS is throwing errors and I have to close + reopen photoshop to get the space back.

And the file size does not translate into the size of the document in memory (or on the scratch disk), plus you have history states taking up some scratch space, and possibly preset you loaded. Files on disk are compressed - and they are uncompressed in memory.

But, none of this has changed.

You might want to check your preferences, and make sure you're using smaller (128K) image tiles to save some space.
